Global Cnc Industries 8601B .187 Tool Holder Bushing Type B

Product Description

The GLOBAL CNC INDUSTRIES 8601B .187 is a Type B rotary tool holder bushing designed to locate and support cutting tools within drill jigs, tool holders, and fixture assemblies. With a 3/16 inch (0.1875 inch) inside diameter and a 3/4 inch (0.7500 inch) outside diameter, this bushing provides precise tool guidance during machining operations. The head thickness measures 0.19 inches and the length under head is 1-1/2 inches (1.5000 inches). Machinists, toolmakers, and CNC setup technicians install this type of component when building or maintaining drill jig fixtures that require repeatable, accurate hole location.

This bushing is suited for use in production drilling, reaming, and boring setups across machine shop environments. Type B bushings are commonly pressed or slipped into liner bushings within jig plates, making them a standard component in fixture fabrication for both short-run and high-volume manufacturing applications. The 3/16 inch bore accommodates tooling of that shank diameter, and the head keeps the bushing positively located against the jig plate surface during operation.

Key Features

• Type B bushing configuration with a headed design for positive axial location in jig plates
• Inside diameter of 3/16 inch (0.1875 inch) for precise tool guidance
• Outside diameter of 3/4 inch (0.7500 inch) for standard liner bushing fitment
• Length under head of 1-1/2 inches (1.5000 inches) suits common jig plate thicknesses
• Head thickness of 0.19 inches provides a low-profile seating surface
• Weighs 0.2 pounds - lightweight for easy handling during fixture assembly

Compatibility

Designed as an OEM-style replacement or direct-fit component for standard Type B rotary tool holder bushing applications in drill jig and fixture assemblies requiring a 3/16 inch bore and 3/4 inch outside diameter.

Installation Notes

Installation is typically performed by toolmakers or machinists during fixture build or maintenance. Ensure the mating liner bushing bore and the jig plate counterbore are clean and free of burrs before seating the bushing. Press or slip the bushing into place per the fixture design specification, and verify that the head seats flush and square against the jig plate surface before use. Follow applicable shop safety procedures when working with press-fit components.
